Need to mirror a port on a switch but do not know if it is even possible - please help

I am trying to troubleshoot an issue we are having when a laptop is connected wirelessly to our network and communicating with a Crestron AirMedia 101 device.  (Everything is okay if the laptop is connected via Ethernet cable to our network.)  I have done a ton of support work with both Crestron and SonicWall.  The latest is, Crestron wants me to identify the two ports to which the AirMedia device and the wireless Access Point (at that location) are connected and then to mirror those two ports into one on an empty port of a switch.

 

Everything on our network is connected to our firewall, a SonicWall NSA5600.  Our wired network at Town Hall is connected to the firewall using interface X0 for our LAN which connects to four stacked Cisco 2960X-48LPD-L switches.  Our Access Points are connected to the firewall using interface X3 for our WLAN which connects to a Cisco 2960CX-8PC-L switch creating a VLAN for Wireless Access.

 

The AM-101 is located on switch two of the stack, it has a static IP address of 192.168.xxx.xxx.  The SonicPoint Access Point in the Auditorium utilizes the 2960CX-8PC-L and has a static IP address of 172.31.zzz.zzz.

 

Since the AP and the AM-101 are connected to two different switches on two different interfaces, is the port mirroring going to be possible?

FYI - if your wlan users are not on the same subnet as the AM101 you wont be able to connect to it?
Can you confirm this is the case?
